DLNA on NixOs, not displayed on Panasonic Smart TV

Help
1

I need some help. DLNA functions perfectly on NixOS. Windows 11 and my Android device detect it without any issue. However, my smart TV fails to recognize miniDLNA on NixOS as a media source.

My Panasonic smart TV, although old, detects all devices except for NixOS. Could this be due to a firewall port problem?

{ config, pkgs, ... }:

{
  # DLNA service: Check if working. Open browser: http://192.168.0.13:8200/
  # Cache location: /var/cache/minidlna/  sometimes deleting it clears it
  # ------------------------------------------------------------------------
  services.minidlna.enable = true;
  services.minidlna.settings = {
    friendly_name = "NixOS-DLNA";

    # https://mylinuxramblings.wordpress.com/2016/02/19/mini-how-to-installing-minidlna-in-ubuntu/
    # "A" for audio    (eg. media_dir=A,/var/lib/minidlna/music)
    # "P" for pictures (eg. media_dir=P,/var/lib/minidlna/pictures)
    # "V" for video    (eg. media_dir=V,/var/lib/minidlna/videos)
    # "PV" for pictures and video (eg. media_dir=PV,/var/lib/minidlna/digital_camera)

    media_dir = [
      "APV,/mnt/DLNA/"                       # Master directory, set APV to filter all
      # "A,/home/tolga/public/Music/"        # Music files are located here
      # "P,/home/tolga/public/Pictures/"     # Pics  
      # "V,/home/tolga/public/Vids/"         # Vidoes files are here
    ];
    
    inotify = "yes";
    log_level = "error";
    announceInterval = 1;
  };

  users.users.minidlna = {
    extraGroups =
      [ "users" "samba" "wheel" "tolga" ]; # so minidlna can access the files.
  };

  networking.firewall = {
    enable = false;
       allowedTCPPorts = [ 139 445 8096 ];
       allowedUDPPorts = [ 137 138 1900 ];
  };

}

Any help be appreciated

cheers
